The geocentric model, which posits that the Earth is at the center of the universe, traditionally included the five planets visible to the naked eye: Mercury, Venus, Mars, Jupiter, and Saturn, along with the Sun and the Moon. In more recent views, it could be extended to include Earth itself, making a total of 8 celestial bodies.
The heliocentric model, which places the Sun at the center of the solar system, also recognizes the eight major planets in our solar system: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. The distinction here is that in the heliocentric model, the celestial bodies revolve around the Sun rather than the Earth.
In summary, both models can refer to eight celestial objects when considering Earth and the seven other major planets. However, in historical contexts, the geocentric model may have traditionally counted fewer planets.
